EFFECT OF INITIAL TEMPERATURE ON COMBUSTION OF AMMONIUM PERCHLORATE
Abstract
Experiments were described with ammonium perchlorate combustion at an initial temperature in the 20-150 degrees centigrade range and pressures up to 350 atm. The purpose was to explain the earlier observed anomalies of combustion characteristics and to explore the possibility of eliminating the upper explosion limit and of increasing combustion stability by increasing initial T. The burning rate U of the compacted 7 mm diameter samples increased, the lower explosion limit decreased, and the region of stable combustion was extended, when initial T was increased. Critical pressure also increased. Unstable combustion of a different kind appeared at initial T of 175 degrees centigrade. The minimum temperature coefficient of the burning rate coincided with the maximum U at 150 atm in the region of stable combustion. The observed anomalies were believed to be the result of combustion inhibition by water accumulated in the reaction zone.
